disconnected from all power sources when opening the unit is necessary.
In order to protect the personnel entrusted with maintenance from electric

WARNING!
Risk of injury from automatically starting components
With some components, an automatic start-up is already started as soon as
the power supply is connected or restored after a power failure. This is done
without first actuating a switch or button and can lead to injuries.
– Make sure that there are no persons in the danger zone.
– Ensure operational readiness before connecting the power supply.
– Take suitable higher-level measures to prevent an automatic restart after a
power failure.
DANGER!
Damage and injuries may occur if installation, maintenance or repair
work is carried out incorrectly

Maintenance and repair work may only be performed by authorised and trained
specialist personnel in compliance with current local regulations.
